Description

Technical Field

[0001] The utility model relates to the technical field of building construction templates, in particular to a combined connector for a disassembly-free template. Background Art

[0002] At present, during the pouring construction of the building's exterior wall, it is necessary to support the casting cavity of the building's exterior wall with formwork, and then dismantle the formwork. According to the functional requirements of the building's exterior wall, decorative exterior wall panels are laid on the exterior facade of the building's exterior wall, and interior wall panels for thermal insulation or sound insulation are laid on the interior facade. With the improvement of the construction method of the building's exterior wall, the exterior wall panels and interior wall panels can be directly supported without dismantling the formwork, and the enclosed casting cavity can be cast to form the building's exterior wall. A stable installation system is formed between the exterior wall panels, the building's exterior walls and the interior wall panels through connectors to ensure the safety of laying the exterior wall panels and interior wall panels.

[0003] In the prior art, such as Figure 1 As shown, when the molds are supported between the non-dismantling exterior wall panels 1 and the non-dismantling interior wall panels 2 to form a casting cavity 4, a plurality of positioning sleeves 8 are evenly arranged in the casting cavity 4, and the non-dismantling exterior wall panels 1 and the non-dismantling interior wall panels 2 are tensioned and positioned by the positioning sleeves 8, and the non-dismantling exterior wall panels 1 and the non-dismantling interior wall panels 2 are connected through a plurality of tensioning screws 9, and the tensioning screws 9 are located in the positioning sleeves 8 and pass out, and the mutual force between the positioning sleeves 8 and the tensioning screws 9 is used to make the non-dismantling exterior wall panels 1 and the non-dismantling interior wall panels 2 form a stable mold support system, which is convenient for filling concrete into the casting cavity 4 and hardening and forming a casting wall sandwich layer 3. After the casting of the concrete is completed, it is convenient to extract the tensioning screws 9 from the positioning sleeves 8. In order to ensure the laying and installation position of the non-dismantling exterior wall panels 1 and the non-dismantling interior wall panels 2, the non-dismantling exterior wall panels 1 and the casting wall sandwich layer 3 are connected by a plurality of anchoring screws 1a. The tail end of the anchor screw 1a is located at the previous position of the tension screw 9, so that the tail end of the anchor screw 1a is threadedly connected to the positioning sleeve 8, and the non-dismantling inner wall panel 2 and the cast wall sandwich layer 3 are connected by a plurality of anchor screws 2a, and the tail end of the anchor screw 2a is located at the previous position of the tension screw 9, so that the tail end of the anchor screw 2a is threadedly connected to the positioning sleeve 8; however, there are the following defects during use: the installation and disassembly of the tension screws are cumbersome, and the anchor screws 1 and 2 are installed after the disassembly, which prolongs the construction period. In addition, the combined connection formed by the anchor screw 1, the positioning sleeve and the anchor screw 2 is prone to thermal bridge effect, resulting in discontinuous insulation of the building exterior wall at the position of the combined connection, which is easy to exchange heat with the external environment, and cannot be used in low-energy, ultra-low-energy and near-zero-energy buildings.

The casting wall sandwich layer 3 is filled in the casting cavity 4 formed between the non-dismantling exterior wall panels 1 and the non-dismantling interior wall panels 2, and the casting wall sandwich layer 3 and the non-dismantling exterior wall panels 1 are tied and fixed by anchor piece 1 5, and the casting wall sandwich layer 3 and the non-dismantling interior wall panels 2 are tied and fixed by anchor piece 2 6, so as to ensure that the installation and construction between the non-dismantling exterior wall panels 1, the casting wall sandwich layer 3 and the non-dismantling interior wall panels 2 are stable and reliable, shortening the construction period, and the combined connector of the present application can avoid the generation of thermal bridge effect, ensure that the insulation of the building exterior wall is continuous at the position of the combined connector, and is suitable for low-energy consumption, ultra-low energy consumption and near-zero energy consumption buildings.

[0033] In this specific implementation mode, Figure 5 As shown, the anchor 5 is a T-shaped column tube, and the T-shaped head end of the anchor 5 is arranged in the non-dismantling exterior wall panel 1. The anchor 5 adopts the T-shaped column tube to reduce weight, and the T-shaped head end of the anchor 5 strengthens the tensile strength between the non-dismantling exterior wall panel 1, ensuring the installation stability between the non-dismantling exterior wall panel 1 and the cast wall sandwich layer 3.

[0034] Further, such as Figure 5 As shown, a plurality of seepage holes 50 communicating with the inner cavity of the anchor 5 are provided on the tube wall of the anchor 5. When pouring concrete into the pouring cavity 4, the concrete can easily enter the inner cavity of the anchor 5 through the seepage holes 50, so that the hardened concrete fills the anchor 5, thereby increasing the connection strength between the anchor 5 and the cast wall sandwich layer 3, and ensuring the thermal insulation continuity between the cast wall sandwich layer 3 and the anchor 5, thereby reducing the thermal bridge effect.

[0035] In this specific implementation mode, Figure 6As shown, the anchor 2 6 is a cylindrical tube, and one side of the pipe end of the anchor 2 6 is threadedly connected to the T-shaped locking head 61. The anchor 2 6 uses a cylindrical tube to facilitate welding and fixing the steel mesh frame 7, and to facilitate installing the non-dismantling interior wall panel 2 on the anchor 2 6, and the T-shaped locking head 61 is used to limit and lock it, which can ensure the installation stability between the non-dismantling interior wall panel 2 and the cast wall sandwich layer 3.

[0036] Further, such as Figure 6 As shown, a plurality of seepage holes 60 connected to the inner cavity of the anchor 2 6 are provided on the tube wall of the anchor 2 6. When pouring concrete into the pouring cavity 4, the concrete can easily enter the inner cavity of the anchor 2 6 through the seepage holes 60, so that the hardened concrete fills the anchor 2 6, thereby increasing the connection strength between the anchor 2 6 and the cast wall sandwich layer 3, and ensuring the thermal insulation continuity between the cast wall sandwich layer 3 and the anchor 2 6, thereby reducing the thermal bridge effect.

[0037] In this specific implementation mode, Figure 5 As shown, a plurality of tie grooves 10 are evenly distributed on the panel surface of the non-dismantling exterior wall panel 1 facing the casting cavity 4. When pouring concrete into the casting cavity 4, the concrete can be easily filled into the tie grooves 10. After hardening and forming, the cast wall sandwich layer 3 and the non-dismantling exterior wall panel 1 are stably and firmly connected, thereby improving the tie strength between the two.

[0038] In this specific implementation mode, Figure 5 As shown, a plurality of tie grooves 20 are evenly distributed on the panel surface of the non-dismantling interior wall panel 2 facing the casting cavity 4. When pouring concrete into the casting cavity 4, the concrete can be easily filled into the tie grooves 20. After hardening and forming, the cast wall sandwich layer 3 and the non-dismantling interior wall panel 2 are stably and firmly connected, thereby improving the tie strength between the two.

[0039] The above is a detailed description of an embodiment of the utility model, but the content is only a preferred embodiment of the utility model and cannot be considered to limit the scope of implementation of the utility model.
